llt is known that doet-ing bodies for hydrozietopleees having e curved bottom mid e sharp-edged loew are not fitted for use es doute es they rise with difficulty from the Water. Floats having' o. smooth bottom. and :i bloed.y slightly rounded vtient-edge have loeeii toned to give satisfaction. These fleets., however, have the tendency to become immersed in, the wzitei, turning the machine over. lo order to avoid this deiigei'ous immeteioii iii the Water the fi'ont pei-t of the wos tamed upward but this ceosed on ioei'eese of the resistance to eil'. Furthermorethe floot was forced to follow the move ments ot the Waves to e eeitoiii degfee so that the dying machines suffered eoiieideiable longitudinal movements and could .not i'eeeli the speed necessary to support the me eiiiiie iii the xiii'. Furthermore, the tops of tlie waives eut by the iront-edge of the iioots not only Iboarden the Hoets lout also ovelidow tile parte behind the Heats and exert o. bed iotilienee upon the sensitive parts of the .motorI and the apparatus. lt may be meotioiied also that the outlook for the evietoi' is veiled by the' spray. li have found that these inconveniences een be avoided by p1' vdiiig tioats consisting of o Wedge-slumped body etonding baci: end suitably arranged between two pla-nes tlie lower of Wliioli is curved upward et its front end ood the up per oi which freins out to e point and ie jpi'ei ei'eioly somewhat Figure Il is ei side elevotioee-l View oin e iiydioaeiropleiie; Fig. 2 is e pei'speetive View et ooe of the Heats; Fig. 3 is e side elei/of tioool View ont' e slightly modified tomi oit idioot; Fig. Il ie e plan View of the tloet eliowo iii Fig. 3. is e offese-eeetiolool `View oo tite liifieeAiT-d 3 eed le lift;
